In that vein....  Why are we _forking_ all of these scripts?

In SVR4, if a rcN.d filename ends in ".sh", it is .-sourced into the main
shell instead of being run.  Though this is oft used for setting variables
in the main shell, it is also a speed hack--if the invocation is done right,
it can function almost like a regular script.

In the main rc:

. /etc/rc.subr
. /etc/rc.conf

In rc.subr, for run_rc_script:

if [ filename ends in ".sh" ]; then
	set -- start
	. $rcfile

...or similar, not in pseudocode.
